When a grand procession is being celebrated at night, one should cut off the nipples of the udder of a dead cow and burn them in a torch-light flame. A fresh vessel should be plastered in the interior with the paste prepared from these burnt nipples, mixed with the urine of a bull. When this vessel, taken round the village in circumambulation from right to left, is placed below, the whole quantity of the butter produced by all the cows (of the village) will collect itself in the vessel.
